Introduction

TCO Certified is an international third party sustainability certification for IT

products. By choosing TCO Certified computers, displays and other devices,

businesses and organizations around the world are able to help meet environmental

and social challenges associated with electronics.

Since the end of the 1980s, TCO Development has advanced the sustainable

development of IT products. Today our international certification system – TCO

Certified – makes it easier to choose sustainably designed and manufactured IT

products such as displays, computers, smartphones and tablets. TCO Certified is a

third party certification, Type 1 Eco Label according to ISO14024.

Sustainability in all phases of the product life cycle

Electronics are associated with many different sustainability risks throughout the life

cycle, including manufacturing, use and end of life phases. Criteria in TCO Certified

aim to address many of these challenges throughout the life cycle, making it the most

comprehensive third party certification for IT products. For each criteria area in this

document, the relevant life cycle phase is indicated by the following icons:

W

i

t

h

e

v

With every major update we aim to enhance the criteria in line with technology

innovation and sustainability challenges. Updates are a result of dialog with key

stakeholders, such as purchasers, users, industry, and subject matter experts. This

criteria document, TCO Certified Projectors 2, is the second version of TCO

Development’s certification of projectors. Moving forward, subsequent versions, 2.1,

2.2 etc., may be released, but will be considered only as updates within the second

version, with improved precision of the mandates and test methods.

Citing from these criteria (e.g. in procurement contracts) is permitted, provided that

the source is disclosed and the extent of the quotation is consistent with sound

copyright practice. For further information, please visit www.tcodevelopment.com.

A Criteria

A.1 General information

This document contains requirements, test methods and references for front screen

projectors with fixed resolution, herein referred to as “projectors” throughout.

Projectors are devices that focus an image onto a screen by projected light. The image

from a light-reflecting screen is viewed from the projector side of the screen (so-called

front screen projection with fixed resolution).

Since Projectors are developed for different purposes and viewing conditions as well as

for use in different ambient lighting conditions, TCO Development has found it

necessary to develop the two following criteria levels:

1. Criteria levels for office projectors

2. Criteria levels for video projectors.

The criteria levels for office projectors are for projectors designed to produce a static

image in a highly illuminated room. The criteria levels for video projectors are for

projectors designed to produce a moving image in darker or sparsely illuminated

rooms. (See References 1 and 2)

The aim of this criteria document is to provide relevant criteria and test methods for

the actual life cycle of the product. This criteria document consists of two parts; Part

A- the mandated criteria and Part B - clarifications and test methods.

Compliance with the mandates in this criteria document is achieved in one of two

ways; either through a test report or through a verification report.

1. A test report is defined as a report based on:

• Testing conducted by the facility issuing the test report for the product

identified in the report.

2. A verification report is defined as a summary report and a verdict (pass or fail)

based on either:

• A test report issued by the same facility

• A test report issued by a different facility.

• Declarations from the Company or Brand owner applying for the

certificate.

The options accepted by TCO Development for each criterion can be found under each

mandate.

A.2 Visual ergonomics

Good visual ergonomics is a very important aspect of quality that can also have a

direct effect on the health, comfort and performance of the user. Good ergonomics,

such as a high quality display image, can also influence our productivity and extend

the usable life of a product. In this way, ergonomic design can also offer

sustainability benefits.

In developing criteria for visual ergonomics TCO Development considered the

various environments the projector would be used in. Other features that characterise

high quality projectors have also been in focus when developing these criteria, with

the goal of simplifying the process of buying a projector. For example, TCO

Development developed an approach that specifies the maximum projected image

size (area m2) which can be verified readable. The term used throughout this criteria

document is for this measurement is: “TCO Image size”.

TCO Development used three main methodologies to determine suitable levels and

test methods for the visual ergonomics criteria:

1. Based on acceptable visual levels, as determined by scientific research.

2. Based on statistics from tests carried out in accordance with TCO

Development, ISO, MPR regulations and from specialized tests.

3. Based on manufacturers’ knowledge and experience. Manufacturers,

consumer groups and other organisations with interests in the visual

ergonomics field have contributed a great deal of valuable information and

ideas throughout the development process.

A.2.1 Light flux characteristics

A.2.1.1 Luminous flux

Background

It shall be possible to have a sufficiently high light flux with respect to the ambient

lighting in order to present a comfortable viewing situation with sufficient luminance

and luminance contrast. Poor light flux can affect legibility and colour discrimination

of the presented image content, leading to misinterpretation and extended visual

work load.

The light flux must be suitable for the viewing conditions. In dim lighting conditions

a too high light flux can be disturbingly high for human eyes that have adapted to the

dim lighting, while a high light flux may be necessary for an adequate image quality

in very bright viewing conditions where the projected light must compete with the

degrading ambient light.

Definition

Amax is the maximum projected image size that is verified readable according to the

TCO criteria, hereinafter named “TCO Image size”. Amax is measured in m².

ambwhite

measuredwhite

ELA

/max

This is the largest “TCO Image Size” that the certificate owner can declare.

However, it may be necessary to declare a smaller “TCO Image Size” in order to

pass other criteria that depend on the “TCO Image Size”, such as black level.

Φwhite/measured is the measured light flux from the projector in lumens falling on a

white screen. (In the calculations the screen is considered to have a Lambertian

surface with gain=1).

Lwhite is the minimum required imaging luminance in cd/m2 of white to achieve

the “TCO Image Size”.

Eamb is the ambient illuminance in lux falling on the white screen.

Both Lwhite and Eamb illuminate the screen image, but Lwhite contributes to the image

because it comes from the projector, while Eamb has no positive imaging affects and

degrades the image from the projector. The Eamb and the Lwhite for the two viewing

conditions used in this document are shown in the table below.

The following light values have been chosen to represent adequate standard viewing

conditions for home video and office environment.

A.2.1.2 Black level and contrast ratio

Background

It is important that a projector can produce a black level dark enough to show

shadow details in pictures at high and low white luminous flux levels. The black

level is also important for achieving a good contrast ratio.

Definition

Black level is the capacity of the projector to maintain a good reproduction of black

even when its luminance is high.

Office projectors shall be able to give a contrast ratio of 5:1 in normal “conference

room” ambient illuminance (100 lux). To achieve this the luminous flux of black

must not be higher than Φblack/max/office

A.2.1.3 Light flux uniformity

Background

Image quality e.g. the identification of individual letters, could be badly affected by

non-uniform image illuminance. When poor image illuminance uniformity is visible,

it can locally affect the contrast and consequently the legibility of information on the

projector. The areas of deviating image illuminance can have different sizes and

cause varying edge sharpness.

Definition

Light flux uniformity is the capability of the projector to maintain the same

illuminance level over the whole projected screen area. It is given as a ratio

according to:

15 (121)

A.2.2 Image detail characteristics

A.2.2.1 Native display resolution requirement

Background

Image quality is negatively affected by a low fill factor, visible “jaggies”, poor

rendering of details, etc. All of these parameters are related to the native resolution of

the projector. For resolution characteristics, it is important to take the viewing

distance into account.

The necessary resolution to avoid a low fill factor resulting in jaggies poor rendering

of details etc is dependent on the viewing distance. If the viewing distance is larger, a

lower fill factor (resolution) can be acceptable.

For most TCO Image Sizes a viewing distance of 1.5 x the diagonal is defined for the

first row of viewers.

However, for very small TCO Image Sizes (e.g. presented by pico projectors) it is

likely that the first row of viewer is slightly further away than 1.5 x the diagonal.

This means that a lower resolution can be accepted for small TCO Image Sizes.

Because of this, the viewing distance in this TCO Certified criteria document is

defined for three different TCO Image Size spans.

Example

To achieve 30 pixels/degree for a 4:3 aspect ratio image with a viewing distance of

1.5 times the diagonal it is necessary to have XGA native resolution. In the same way

it is necessary to have SVGA native resolution if the viewing distance is increased to

1.8 times the diagonal and VGA native resolution is acceptable if the viewing

distance is increased to 2.2 times the diagonal.

This means that if the intended use is to project 4:3 images of 0.5m2 it is enough with

VGA native resolution. If the intended use is to project larger images than 1.5m2 it is

necessary with XGA resolution.

For other aspect ratios the minimum accepted resolution must be calculated

according to the formulae in B.2.2.1.

Definition

A pixel is the smallest addressable imaging element of the digital picture capable of

reproducing a full range of luminance and colours.

The native resolution is the actual, true, physical resolution of the projector. The

projector will never be able to display more actual pixels than it has on those panels

or chips.

Viewing distance is the distance between the screen and first row of viewers.

Applicability


Test procedure

16 (121)

Mandate A.2.2.1:

The projected image shall have a pixel density 30 pixels/degree visual angle. To achieve this the necessary native resolution is dependent on the viewing distance.

For projectors with a declared TCO Image size ≥ 1.5 m2 (≈ 70” diagonal) the viewing distance

is considered to be 1.5 x diagonal of the TCO Image Size. (This corresponds to at least XGA for

4:3).

For projectors with a declared TCO Image size < 1.5 m2 (≈ 70” diagonal) the viewing distance

is considered to be 1.8 x diagonal of the TCO Image Size. (This corresponds to at least SVGA for

4:3).

For projectors with a declared TCO Image size ≤ 0.5 m2 (≈ 40” diagonal) the viewing distance

is considered to be 2.2 x diagonal of the TCO Image Size. (This corresponds to at least VGA for

4:3).





17 (121)

A.2.3 Colour characteristics

A.2.3.1 Correlated colour temperature, CCT variation

Background

If the Projector is equipped with pre-set correlated colour temperature settings the

user has the right to expect that the colour hue of the measured correlated colour

temperature setting is close to the one indicated by the pre-set. This makes it possible

to more accurately evaluate the colour of an image on the Projector compared to real

scenes or prints.

Physical measurements of colour stimuli can only give an indication of the colour

appearance in a practical situation. The colour of a frame, the spectral composition of

the lighting, the colour of various areas in the visual field, and the complexity of

brightness variations in the visual field all influence the colour appearance of a

projector image.

The colour rendering of the projected image is very dependent on the screen used.

Normal daylight has a correlated colour temperature in the range 5000 – 10000 K. As

an example, the daylight on a cloudy day at midday is about 6500K.

Definition

The correlated colour temperature CCT is the temperature of the Planckian radiator

whose perceived colour most closely resembles that of a given (whitish) stimulus at

the same brightness and under specified viewing conditions.

Applicability


Test procedure

Mandate A.2.3.1:

The correlated colour temperature of the projected bright white image shall be in the range of 5000K to 10000K.

Each pre-set correlated colour temperature shall have a colour difference u´v´ 0.015 when compared to CIE u´ and v´ chromaticity co-ordinates for corresponding correlated colour temperatures.





18 (121)

A.2.3.2 Colour uniformity

Background

The human visual system is very sensitive to changes in colour hue in white and grey

areas. Since the white or grey colour hues are the background on which most colours

are judged, the white or grey areas are the reference colours of the image.

Patches of colour variation on an active white or grey image could reduce the

contrast locally, be disturbing and affect the legibility, colour rendering and colour

differentiation.


Definition

The colour uniformity of a projector is the capability to maintain the same colour in

any part of the projected image area.

Mandate A.2.3.2:

u´v´ 0.015 for the maximum colour deviation between measured active areas on the TCO Image Size that is intended to maintain the same colour.





19 (121)

A.2.3.3 Colour gamut

Background

Accurate colour rendering is important when realistic colour images or colour

presentations are to be presented using the projector. Poor colour rendering can lead

to poor legibility and misinterpretation. The u' and v' chromaticity co-ordinates of the

primary colours red (R), green (G) and blue (B) of the projected image shall aim at

values given in international IEC, EBU and ITU standards. The u' and v'

chromaticity co-ordinates of the primary colours R, G and B form a triangle in the

CIE 1976 uniform chromaticity scale diagram. The larger the area of the triangle, the

wider the range of colours the projector is capable of presenting.


Definition

The colour characteristics of a projector are based on the visual appearance of the

Projector primary colour stimuli, the R, G, B-stimuli.

A.2.3.4 Colour greyscale linearity

Background

A well-tuned colour greyscale is the basis for good colour rendering of any imaging

device. This is measured via steps in a greyscale in the test image. Each greyscale

step shall have similar colour hues in order to simplify colour interpretation and to

avoid confusion for the user. Only the luminance shall vary (within acceptable

limits).

The colour rendering of the projected image is very dependent on the screen used

Definition

Colour greyscale linearity is the capability of the imaging device to maintain the

same u', v' coordinates of a greyscale pattern at all tested greyscale levels, i.e. only

the luminance shall change from one greyscale step to the next.

A.2.4 Compatibility characteristics

A.2.4.1 Video- and computer interfaces

Background

Interactivity across work devices is very important. Users should find it easy to

securely connect a projector to an external device in order to show both video and

computer signals. Therefore, in the case of projectors, it is important that suitable

interfaces are available for the most common video- and computer signals, e.g.

s-video, component, VGA, DVI and HDMI. Developments in the wireless market are

making advances. However, for this version it is considered too soon to require that

all TCO Certified Projectors be equipped with wireless technology.

Definition

An interface is a system of standardised regulations for devices to handle electrical

signals and physical connections. These are different for video and computer

purposes.

Applicability


Test procedure

Mandate A.2.4.1:

A projector shall have at least one interface for video signals and one interface for computer signals following common standards.

A.4 Emissions

Users of IT equipment increasingly have several nearby electrical and magnetic field

sources placed on work surfaces that they are exposed to. When the first TCO

certification for IT products was introduced in 1992, one of the main issues was the

criteria for reducing electrical and magnetic fields. To this day scientists and experts

are divided on the question of whether these fields pose any risks to human health.

Due to continued public concern and the increasing amount of emissions surrounding

us, TCO Development remains convinced that the criteria in TCO Certified are still

relevant, even with today’s ‘slimline’ low emission products. TCO Certified

emissions criteria are intended to make certain that internal shielding is used to

ensure that a TCO Certified product’s emissions are at a technically achievable low

level and will not raise normal background levels when the product is used in a

working environment.

TCO Certified criteria cover emissions around the certified product since it may be

placed near other persons working in close proximity.

Many people find acoustic noise annoying, especially high pitched noise. To prevent

this problem, TCO Development sets criteria for products with integrated fans.

A.4.1 Alternating electric fields

Background

Electrical alternating fields are created between objects that have different levels of

electrical potential which change over time. When the potential changes in a periodic

manner, an electrical alternating field is set up, with a field strength and a frequency.

An IT product can contain many sources of electrical alternating fields. The field

characteristics depend on the actual electrical potential difference and the distance

from the product.

Some users are concerned about a possible health risk arising from electrical

alternating fields generated by IT products. The mandatory criteria are aimed at

reducing the electrical alternating fields to such a low level so as not to burden the

work and home environment with unnecessary factors. The mandatory criteria shall

not be regarded as hygienic limit values.

Applicability


Test procedure

See B.4.1.

Mandate A.4.1:

Band II: 2 kHz to 400 kHz, 1.0 V/m measured at 1 m around and topside of the projector.





24 (121)

A.4.2 Alternating magnetic fields

Background

Magnetic alternating fields are created when an electrical alternating current flows

through a conductor. IT products are surrounded by magnetic alternating fields.

These magnetic alternating fields are generated by different parts of the product, e.g.

external power supply unit, voltage inverters and other electrical circuits. The field

strength depends on the actual electric current and on the distance from the product.

Some users are concerned about a possible health risk arising from electrical

alternating fields generated by IT products. The mandatory criteria are aimed at

reducing the magnetic alternating fields to such a low level so as not to burden the

work and home environment with unnecessary factors. The mandatory criteria shall

not be regarded as hygienic limit values.

Applicability


Test procedure

See B.4.2.

Mandate A.4.2:

Band I: 5 Hz to 2 kHz, 200 nT, measured at 1 m around and topside of the Projector.

Band II: 2 kHz to 400 kHz, 25 nT measured at 1 m around and topside of the Projector.





25 (121)

A.4.3 Acoustic Noise

Background

Acoustic noise from fans can be disturbing. To prevent such disturbance, projectors

should cause a minimum of noise during usage. In this criterion the sound power

level is required since this includes the total noise emitted from the projector and

describes the noise characteristics of the projector in the most reliable way. Sound

power level is the only value that can be used to compare different products.

Definitions

A-weighted sound power level (LWA) in decibels: The sound power level of the

projector, determined in accordance with ISO 7779:1999, with A weighting. The

reference sound power is 1 pW.

Declared A-weighted sound power level (LWAd): in bels (B). Defined in accordance

with ISO 9296:1988 3.2.5. NOTE: besides the unit bels (B) a declaration in decibels

(dB) is common.

Operating mode. A condition in which the system shall be operated in accordance

with ISO 7779:1999 C.15.3.2 and C.9.3.2.

Idling mode. A condition in which the system shall be operated in accordance with

ISO 7779:1999 C.15.3.1.

Eco Mode. A reduced power state that the projector enters on the user’s initiative

following the manufacturer’s instructions. Eco mode is when the projector consumes

less energy, the acoustic noise level is reduced and the possible life of lamp is

increased than in on mode.

Applicability

A.6 Environment

This section details the environmental criteria in TCO Certified, which offer a

unique, integrated balance of environmental issues in the manufacturing, use and end

of life phases of the product.

The environmental criteria are divided into the following sections:

1. Manufacturing – criteria focusing on the manufacturing phase and

environmental management

2. Climate – energy consumption, one of the most important issues in the

environmental impact of IT products.

3. Hazardous Substances – heavy metals, flame retardants, plastics.

4. Material resource efficiency – factors to extend the life of the product and

influence better use of material resources.

5. End of life – factors to stimulate recycling and minimize the impact of e-waste.

Potential environmental effects are evident at each stage of the product life cycle.

The environmental criteria TCO Development has focused on in this document are

those that we consider most relevant to the product group. They have also proved to

be attainable in volume manufacturing and are verifiable. Future criteria updates will

likely focus on the manufacturing phase, hazardous substances and climate issues.

Compliance with these criteria (except section A.6.3 Climate) is verified by sending

the requested information to a verifier approved by TCO Development. The energy

consumption requirements in section A.6.3 shall be tested at a test facility approved

by TCO Development or an EPA approved test facility.

A.6.4.2 Halogenated substances

Background

Halogenated flame retardants and plasticizers are often persistent, can bio-

accumulate in living organisms and have been detected in both humans and the

environment. These substances may be problematic in the manufacturing and end of

life phases where workers or the environment can be exposed. They can also migrate

from the products during the use phase with unknown health effects as a result.

Definitions

Plastic parts are parts made mainly of plastics, e.g. the housing. Parts containing

other materials in any significant amounts, e.g. cables with metal conductors, are not

included in the definition.

Printed wiring board laminate is a printed board that provides point-to-point

connections but not printed components in a predetermined configuration on a

common base.

Halogens are a group of five chemically related non-metallic elements in the

Periodic Table; fluorine, chlorine, bromine, iodine and astatine.

Polybrominated biphenyls (PBB) and Polybrominated diphenyl ethers (PBDE) are

restricted in the RoHS directive (2002/95/EC) due to the hazardous properties of

these substances. Hexabromocyclododecane (HBCDD) has been identified as a

A.6.5 Material Resource Efficiency

A.6.5.1 Lifetime extension

Background

A longer product lifetime makes a significant positive contribution to more efficient

resource use as well as the reduction of air and water pollution. A pre-condition for

prolonged lifetime is that the product is of high quality, which is supported by good

warranties. Another requirement is the availability of spare parts for a number of

years once it is taken out of production. During this period, products should, if

possible, be repaired and not replaced.

Definitions

Brand owner: The company or organization owning or controlling the Brand Name.

Brand Name: The name or sign, including but not limited to a trademark or company

name, used to identify, amongst users and customers, the manufacturer or seller of a

product.

Product Warranty is a period where the Brand owner offers to repair or replace

broken products during a period of time at no charge.

Spare parts are those parts that have the potential to fail during normal use of the

product. Product parts whose life cycle usually exceeds the average usual life of the

product need not be provisioned as spare parts. When the cost for replacing a broken

part (e.g. panel) exceeds the cost of replacing the whole product, then that part need

not be considered as a spare part under this mandate.

A.6.6.2 Take back system

Background

The amount of electronic waste in the world today is enormous and a growing

environmental problem. It is important that manufacturers provide mechanisms to

take back their equipment at end-of-life under the principle of individual producer

responsibility wherein each manufacturer must be financially responsible for

managing its own branded products at end-of-life. Currently much electronic waste is

being exported to developing countries where it is managed unsustainably and

disproportionately burdens those regions with this global environmental problem.

The Basel Convention and its decisions govern the export of many types of

electronic waste, however it is not properly implemented in all countries. With this

mandate TCO Development aims to influence the expansion of better electronic

waste management practices to more countries.

Definition


Brand Name: The name or sign, including but not limited to a trademark or company

name, used to identify, amongst users and customers, the manufacturer or seller of a

product.

Take back system is a system that makes sure that the customer can return used

products to be recycled. The system can be with or without a fee.

Environmentally acceptable recycling methods are:

Product and component reuse

Material recycling with secured handling of hazardous chemicals and heavy

metals

Pollution-controlled energy recovery of parts of the Projector

A.7 Socially responsible manufacturing

Shorter product cycles and growing demand for new technologies put increasing

pressure on industry and its complex supply chain to deliver new devices faster and

at a low cost. The result is often inadequate working conditions at manufacturing

facilities, long working hours, low wages and a lack of health and safety measures.

TCO Development aims for greater brand engagement throughout their supply

chains by setting criteria and verification routines that create strict social policies

toward suppliers, as well as factory audit structures and an open dialog within the IT

industry.

Life Cycle Phase



58 (121)

A.7.1 Supply chain responsibility

Background

It is TCO Developments opinion that codes of conducts and factory audits are

currently the tools that are most practical to help the majority of brands to work with

socially responsible manufacturing in a structured way. It is also TCO Developments

opinion that these tools are improving the situation incrementally as long as they are

used in the correct and committed way by the brand.

The contribution of TCO Certified is:

TCO Certified defines a minimum level of the Brand owner’s code of

conduct.

TCO Certified is a control system to ensure that the brand takes the

responsibility and work in a structured way in accordance with their code of

conduct.

TCO Certified creates an incentive for Brand owners to work proactively.

Definitions


First tier manufacturing facility: Manufacturing plant where the final assembly of the

TCO certified product is taking place.

Corrective action plan: A list of actions and an associated timetable detailing the

remedial process to address a specific problem

Applicability

The Brand owner.

A.7.3 Conflict minerals

Background

The exploitation and trade of the natural resources, Tantalum, Tin, Tungsten and

Gold (3T+G) from conflict-affected areas is commonly regarded as a major source of

conflict financing. TCO Development supports the underlying goal of the EU

conflict minerals measures and those contained in the Dodd Frank Act 1502, but

believe it is also vital to support in-region responsible sourcing programs in order to

help suppliers meet these Due Diligence requirements, maintain trade and develop

mining that directly benefits the people whose livelihoods depend on a legitimate

trade. TCO Development now requires all Brand owners who use TCO Certified to

address the issue of conflict minerals in their certified products in a progressive and

proactive way.

B.0.3 Conditions for the equipment under test

The projector being tested shall be physically prepared for testing and shall be

warmed up until it is fully stabilised, but at least for 30 minutes and after lamp

aging (see B.0.6).

The projector lens surface shall be clean when tested.

The projector shall be tested under nominal conditions of input voltage, current,

etc. If sold on different markets, one setup shall be chosen by the manufacturer

which shall represent the conditions of the country in where it will be sold the

most.

The projector shall be connected to a computer, if the manufacturer does not

specify a different presentation host. Within the computer a graphics board of

high quality, which offers a digital output and a typical output voltage on RGB of

0.7 V ± 10% shall be used.

When possible testing shall be done with the digital signal input. In the case of

several digital inputs the one with the lowest bandwidth which can still support

the native resolution shall be used. The same signal input shall be used for testing

of all parameters. The signal input used shall be specified in the test report.

A video generator shall not be used to drive the projector

B.0.4 Projector alignment for testing

The distance between front lens of the projector and the measurement plane

(screen), the throwing distance, should be according to manufacturer’s

specifications.

The measuring plane shall be perpendicular to the optical axis of the projector

lens, if not specified otherwise in the test method. The measuring plane shall be

defined as the focus plan at the centre of the projected image.

The image shall be focused and the main focus shall be set for the centre of the

image. Use a test image containing both horizontal and vertical black and white

details of different sizes. If no change of focus arises during the test period, no

refocusing should be necessary between the different tests.



71 (121)

B.0.5 Instruments used for testing

All instruments used for testing of a projector shall be of good quality and validated

by a recent test certificate from a certified testing facility. Any necessary instrument

calibration shall be done before the tests are performed. Calibrations shall be

traceable to international standards. The instruments shall not be used handheld, but

be mounted or stabilised by some sort of support, i.e. a tripod.

The surface of the sensor of the illuminance meter shall be parallel to the screen

surface. The flat detector surface is supposed to simulate a small screen, and

consequently be positioned as such. Make sure not to shadow the illuminance

meter or get in front of it so that you reflect a bunch of light into the illuminance

meter.

B.0.6 Settings of the Projector

The Projector resolution shall be set to the native resolution.

The projector shall be put in its factory default mode. The CCT of the default

mode shall be used. All tests shall be performed with the projector settings set in

the factory default mode if not stated otherwise in the test methods.

B.2 Visual ergonomics B.2.0 General test conditions for visual ergonomics

B.2.0.1 Basic test requirements

As described in section B.0.

B.2.0.2 Photometric test facility general requirements

Photometric measurements shall be performed under darkroom conditions. This

means that measurement data shall not be affected by direct light from sources or

light reflected from interiors, equipment, clothes etc.

(All calculations shall correspond to a projector screen with a gain=1.0.)

B.2.0.3 Power supply and test room climate requirements for testing

AC mains voltage* 230 VAC RMS, tolerance 1 %

AC mains frequency* 50 Hz, tolerance 2 %

Test room temperature 23 ± 4 ºC

Humidity 10-85 % RH (non-condensing)

* – or other voltage and frequency combination specified by the client.

B.2.0.4 Photometric and spectrometric measurements

Several instruments are to be used when carrying out measurements for visual

ergonomics. All instruments shall be recently calibrated and carry a calibration

certificate from a certified testing facility. No photometric instruments shall be used

handheld, but be mounted or stabilised by some sort of support, i.e. a tripod.

The following instrument types shall be used for testing:

Illuminance meter. An illuminance meter shall have a V()-sensitivity

(Requirements for luminance meters are covered by CIE Publication 69 (1987).

Illuminance meters of CIE Class A (with a combined performance characteristic 5

% shall be used.). The illuminance meter must incorporate an appropriate time

constant of integration in order to ensure averaging of the pulsation of the light

emitted by projectors. Use a cosine corrected illuminance meter. The illuminance

meter shall be calibrated both at very low and high illuminance levels. No

illuminance meter shall be used handheld, but be mounted or stabilised by some sort

of support, i.e. a tripod.

Colour neutral reflectance standard. The colour neutral reflectance standard shall

have a reflectance factor of 0.95 0.05 and vary 0.01 within the wavelength

interval 380 nm till 780 nm and be calibrated to the angles involved. This shall only

be used for colour measurements as the reflectance standard may be unreliable for

luminance measurements at certain angles.



75 (121)

Spectro-radiometer. An instrument for the measurement of radiant flux as a

function of wavelength shall be used. A spectro-radiometer for the measurement

of light and colour is normally equipped with a microprocessor that makes it

possible to obtain luminance and colour co-ordinates directly from raw

measurement data. A spectro-radiometer can replace the luminance meter when

suitable. The wavelength resolution shall be at least 4nm for accurate colour

measurements. The sensitivity shall be independent of the polarization of the

measured light (often referred to as f8 error). No spectroradiometer shall be used

handheld, but be mounted or stabilised by some sort of support, i.e. a tripod.

The relevant CIE material – conversion formulae and tabulated data for u'CCT and

v'CCT – can also be found on the TCO Development Web site,

www.tcodevelopment.com. A computer program based on the given equations can

be supplied by TCO Development.

B.2.0.5 Stray light

Stray light may cause errors which can negatively affect measurement of illuminance

and chromaticity coordinates. It is therefore necessary to make an evaluation of stray

light influence for the different measurement procedures described in this document.

If it is verified that stray light affects the measurement result it is necessary to take

actions to eliminate the source of error. One possible way to solve the problem is to

use a lab with low reflections from walls, floor and ceiling or a much larger room (an

infinitely large room with white walls is black).

The lightproof room shall fulfil the requirements given by IEC 61947-1 clause 4:

Less than 1% of the light on the screen where a white image is projected shall be

from any source other than direct light from the projector.

For contrast ratio measurement, less than 10 % of the light on the screen where a

black image is projected shall be from any source other than direct light from the

projector.

B.2.0.6 Overall uncertainty

The overall uncertainty of the test facility shall be calculated for each measurement

procedure in this document and presented in the test report. The uncertainty shall be

within the required levels for each criterion. All measurement uncertainties claimed

for used instruments shall be referred to traceable calibration reports.

About combining overall uncertainty values during test measurements:

Criteria are fulfilled without adding or subtracting the measurement uncertainty.

Report the value shown on the instrument without adding or subtracting the

measurement uncertainty.

The measurement uncertainty of the test facility shall be printed in the test report

together with the reported value.

For a test facility that has an overall measurement uncertainty higher than the one

allowed by TCO Development for a certain criterion, then the test report for that

criterion is not valid for certification and the test result will not be accepted by

TCO Development.

B.2.1.3 Light flux uniformity



The default test image is a full-screen with colour “bright white” (RGB setting of

255, 255, 255). The size of the test image shall be the “TCO image Size”.

However, if the test facility is not large enough to project the “TCO Image Size”

it is allowed to do testing on an image size larger or equal to 50% of the “TCO

Image Size”.

B.2.1.3.2 Equipment:

Illuminance meter.

B.2.1.3.3 Test method:

The illuminance is measured at location 1 to 9 according to figure B.2.1.1.

It is not recommended to perform this parameter together with B.2.3.2 Colour

uniformity, since the reflectance standard used in B.2.3.2 Colour uniformity is

likely not calibrated for the angles involved and consequently will give false

luminance results for the light flux uniformity.

B.2.2 Image detail characteristics

B.2.2.1 Native display resolution requirement


No specific preparation of the projector is needed.

B.2.2.1.2 Equipment

Calculator and projector manual or similar information about the resolution of the

projector.


The maximum resolution and frequencies of the projector are found in the manual or

similar information from the manufacturer.


For TCO Image sizes equal to or larger than 1.5 m2 a viewing distance of 1.5 times

the diagonal is defined for the first row of viewers.

However, for very small TCO Image Sizes (e.g. presented by pico projectors) it is

likely that the first row of viewer is slightly further away than 1.5 times the diagonal.

This means that a lower resolution can be accepted for small TCO Image sizes.

Because of this, the viewing distance in this TCO criteria document is defined for

three different TCO Image Size spans.

Example:

To achieve 30 pixels/degree for a 4:3 aspect ratio image with a viewing distance of

1.5 times the diagonal it is necessary to have XGA native resolution. In the same way

it is necessary to have SVGA native resolution if the viewing distance is increased to

1.8 times the diagonal and VGA native resolution is acceptable if the viewing

distance is increased to 2.2 times the diagonal.

This means that if the intended use is to project 4:3 images of 0.5m2 it is enough with

VGA native resolution. If the intended use is to project larger images than 1.5m2 it is

necessary with XGA resolution.

The minimum resolution to fulfil the criteria can be calculated for any aspect ratio in

the following way:



83 (121)

Minimum amount of pixels in the vertical direction

Half the TCO Image Size height at the viewing distance expressed in degrees is:

arctan(width/2/viewing distance)

The whole TCO Image Size height expressed in degrees is:

2 arctan(width/2/viewing distance)

The requirement is 30 pixels/degree which gives the amount of pixels needed in the

vertical direction to:

30 2 arctan(width/2/viewing distance)

Example:

For the format 5:4:3 and viewing distance 1.5 this gives the formula:

30 2 arctan(4/2/(1.5 5)) = 896 pixels

The principle is the same in the vertical direction.


Uncertainty is not applicable in this case. Product data information is sufficient.

Spectro-radiometer capable of presenting CIE u' and v' chromaticity co-ordinates

with at least 3 decimals.

Colour neutral reflectance standard.


Place the colour neutral reflectance standard in the centre of the projected image (at

measurement location 5 figure B.2.1.1.). Measure the spectral properties at the centre

of the colour neutral reflectance standard with a spectro-radiometer.

The spectral data shall then be processed, which is normally done directly in the

instrument microprocessor, to give chromaticity co-ordinates. In this case the CIE

co-ordinates u' and v' are needed for the test evaluation and are often presented

directly by the spectro-radiometer used.

If the client has stated pre-set CCTs, preparation and testing shall be repeated for all

additional CCTs

The following rules shall apply:

The recommended default CCTs is 6500 K, but the CCT can be anywhere

between 5000 K and 10000 K.

Only CCTs with exactly specified numerical values have to fulfil the

requirements for Pre-set CCTs.

CCTs lower than 5000 K shall not be tested.



85 (121)


The measured u'm and v'm values of the screen for the pre-set CCT and the CIE

reference chromaticity co-ordinates u'CCT and v'CCT values for the reported CCT shall

be used to calculate the colour difference as follows:

22'''''' mCCTmCCT vvuuvu

This calculation shall be done for all tested pre-set CCTs.

The CIE 1976 u' and v' reference chromaticity co-ordinates for five common CCTs

are given in Table B.2.3.1.1.

5000 0.2091 0.4882

If preset CCTs other than those given in Table B.2.3.1.1 are used in the test, u'CCT and

v'CCT can be found by using CIE tabulated data or by using CIE formulae presented

in CIE Publication 15.2 (1986), Colorimetry, p.11, p. 27-28 and p. 53-54, Table 1.3.

If the spectro-radiometer used can only produce CIE 1931 x and y chromaticity co-

ordinates these can be transformed to u' and v' chromaticity co-ordinates by using the

formulae in the CIE Publication 15.2 mentioned above.

The relevant CIE material – conversion formula and tabulated data for u'CCT and v'CCT

– can also be found on the TCO Development homepage,

www.tcodevelopment.com. A computer program based on the given equations can

be supplied by TCO Development.

The resulting colour difference calculation shall be presented to 3 decimal places.

If no pre-set correlated colour temperature exists, report the measured correlated

colour temperature.

B.2.3.2.2 Equipment





The colour uniformity shall first be evaluated visually by the technician in order to

find those areas where the colour varies the most. The most applicable of the

following colour uniformity test shall then be performed.

Measure the chromaticity co-ordinates u' and v' in the visually most colour-deviating

areas. Then, in addition to this, measure the chromaticity co-ordinates in the corner

positions as shown in Figure B.2.1.1 and in the centre.

It is not recommended to perform this parameter together with B.2.1.3 Light flux

uniformity, since the reflectance standard is likely not calibrated for the angles

involved and consequently will give false luminance results for the light flux

uniformity.


u'v' according to the CIE (1976) uniform chromaticity scale diagram shall be

calculated for each measured position using the formula

22'''''' BABA vvuuvu

where A and B are the two points found to have the largest colour difference between

them.

The largest difference in u'v' value shall be reported.

The result shall be presented to 3 decimal places.

example below

The largest u' difference, u', is 0.005 (between 0.190 and 0.185) at measurement

positions 1 and n-1.

The largest v' difference, v', is 0.015 (between 0.447 and 0.432) at measurement

positions 1 and n.

Since v' (= 0.015) is much larger than u' (= 0.005), the v' value shall be used for

the calculation of u'v'.

The corresponding two pairs of u' and v' to be used for the calculation are thus the

values found at position 1 and position n and thus become the values used for points

A and B such that

u'1 = u'A = 0.190 and v'1 = v'A = 0.447 for point A in this example

and

u'n = u'B = 0.186 and v'n = v'B = 0.432 for point B in this example

Hence u'v' = 0.000225 0.000016 = 0.01552, which shall be reported as 0.016.)

TCO will provide an excel spread sheet at the TCO website

www.tcodevelopmet.com which will calculate the ∆ u’ v’ differences between all

the greyscale levels according to the equation:

Fill in the chromaticity values of u’ and v’ for each measured greyscale step into

the corresponding cells of the spread sheet.

The table below contains coloured cells indicating difference requirements. The

principle is that the darker the greyscale the more difficult it is to see a colour

difference.

Examples on how to use the table: By using the column 255 (greyscale 255) and go

down to line 165 (greyscale 165) you find that the maximum allowed colour

difference Δu´v´ is 0.020 (orange cell). For the greyscales 225 and 75 the maximum

allowed difference is 0.035 (green cell).

B.4 Emissions

B.4.0 General test conditions for emissions

B.4.0.1 Basic test requirements

As described in section B.0.

For the test methods for emissions described in this document the following

conditions apply:

AC mains voltage* 230 VAC RMS, tolerance 1 %

AC mains frequency* 50 Hz, tolerance 2 %

The equipment shall be connected to phase and neutral.


B.4.0.2 Conditions and set up for the test object

The tests shall be performed with the full TCO Image Size activated.

The projector control settings shall be the same as for visual ergonomics. This means

the light flux test image at the default setting shall be used for the emission testing of

alternating electric and magnetic fields. See section B.0.6 for details concerning this

setting.

The projector shall focus the test image defined in B.2.1.1.

The projector must comply with the mandatory requirements without having to rely

on an earth connection via the signal cable. In order to test a projector without an

earth connection via the power cable, a battery operated computer, with no

connection to earth, can be used to operate the projector.

If the projector is connected to mains via a detachable mains cord, the measurement

shall be performed with a shielded mains cord of normal type, (connected to earth for

CLASS I device). Shielded power cords have the text “shielded” printed on them.

The shielding shall be of such quality that when the cable is measured by itself,

hanging in its correct position at the turn table but with the test sample removed, the

values shall be below the accepted background level (2.0 V/m in band I and 0.20

V/m in band II).

A projector without an external power supply shall be connected to mains via the

above mentioned power cable, which shall run from the point of its connection on the

projector and then horizontally straight to a point 0.4 m behind the projector surface.

The cable shall then from this point run downwards at least 1 m. – see figure

B.4.0.2.1.



92 (121)

Figure B.4.0.2.1 Projector without external power supply units.

If the projector is provided with a fixed holder for the power and signal cables, to

secure them together, then this holder is to be used during the test.

The external power supply unit, if any, will contribute to the electromagnetic fields

around the projector. External power supply units, which are connected via a primary

cable to the outlet, shall be positioned centrally, directly behind the test sample, on

the (turn)table, with the secondary side towards the projector. The primary cable

shall extend horizontally, on the (turn)table to a point 0.4 m behind the screen

surface. The cable shall then, from this point run downwards at least 1 m. If the

power supply can be positioned with different sides up, it shall be tested in all

positions and the worst case shall be used. However, if it is obvious which side is

intended to be the top side or bottom side by the placement of LED indicator or

integrated supports to stand on, it is enough to test the power supply in the one

intended position.

The secondary cable of the power supply shall run the shortest distance from the

point of its connection on the projector to the secondary side of the power supply.

The unused portion of the secondary cable, if any, shall be bundled together with the

power supply unit. The bundle loops shall have a length equal to the longest

dimension of the power supply. For supply units with dimensions less than 0.1 m, a

0.1 m bundle loop length shall be used.

primary cable, the secondary cable shall run vertically down to the (turn)table from

the point of its connection on the projector and then horizontally straight to a point

0.4 m behind the projector surface. The cable shall then, from this point, run

downwards at least 1 m.

For measurements of alternating magnetic fields (B.4.2) the power cable may be

positioned in another way, as the cable contributes a negligible amount to the

magnetic field. However external power supplies must be correctly positioned, as

they may give rise to magnetic fields.

If positioning in accordance with the above rules is not possible, then the positioning

of the supply unit and cables shall be described in the test report.

B.4.0.3 Emission measurement instruments

The instruments used for emission testing shall comply with the requirements and

calibration procedures described below:

Alternating electric field meter

The alternating electrical field emission from the projector under test shall be

determined by measuring the displacement current passing a given surface of the

measuring probe. The probe consists of a disc of double sided printed circuit

board laminate with a diameter of 300 mm. On the front of the board the copper

layer is removed in the annulus between radii 50 and 52 mm, see Figure

B.4.0.3.1.

The copper foil surrounded by the annulus is the active measuring surface. It is

connected to one input terminal of an operational amplifier, with capacitive

feedback. The other input terminal of the operational amplifier, the copper ring

outside the active surface, and the back of the board are connected to ground.

The output voltage (U) from the probe (active surface with area (A)) is related to

the incident electrical field, E, averaged over the active surface in accordance

with

U = × E× A/C where C is the capacitance in the feedback loop of the

operational amplifier and is the permittivity for a vacuum.

Figure B.4.0.3.1 Sketch and circuit principle of the Alternating electric field meter for

alternating electrical field measurements. The feedback circuit of the operational

amplifier is a capacitance C in parallel with a high value resistor R to ensure that there

is no DC voltage across the plates of the capacitor C.

The specifications for the frequency response of the alternating field meter are given

by the calibration procedure. The signals from the probe shall be filtered by high-

pass and low-pass filters. The specification of the filters is given in Table B.4.0.3.1.

Attenuation > 80 dB/decade 3 dB 0 dB 3 dB > 40 dB/decade

After amplification and filtering the output voltage of the measuring probe shall be

used to determine the r.m.s. value of the electric field strength in both frequency

bands.

The measuring time shall be sufficiently long to enable measurements with an

accuracy of ± 5 % at 50/60 Hz.

The measuring system shall be capable of measuring at least down to 2.0 V/m in

band I and down to 0.20 V/m in band II.

The measuring probe shall be calibrated using a parallel plate capacitor (air

dielectric) consisting of the measuring probe and a metal plate of at least 300 mm

diameter. The distance between the surface of the probe and the plate shall be 30

mm.

The calibration shall be performed with sinusoidal fields at the amplitudes and

frequencies specified in Table B.4.0.3.2.

Band II 15, 30, 60,120 kHz 1.0, 2.5, 10 V/m

Recorded values at these calibration points shall be within ± 5 % of the nominal

value. Due to the nature of the specified filters the deviation shall be calculated at 1

kHz from 9.5 and 22.5 V/m and at 120 kHz from 0.95, 2.4 and 9.5 V/m.

Alternating magnetic field meter in band I and band II

The magnetic field shall be measured using coil systems that shall consist of three

mutually perpendicular concentric circular coils each with an area of 0.01 m2. The

coils may depart from a circular shape where they intersect. The minimum inner

diameter shall be 110 mm and the maximum outer diameter 116 mm. The measuring

coils shall not be sensitive to electric fields.

The resonance frequency of each coil appropriately connected to cables and

amplifiers shall not be so low that it may influence the specified frequency response

according to table B.4.0.3.1.

Amplifiers and integrating networks to make the output voltage proportional to the

magnetic flux density and independent of frequency shall follow each coil. The

specifications in respect of the frequency response are given in the calibration

procedure.

High-pass and low-pass filters shall filter the signals from the coil systems. The

specifications of the filters are given in Table B.4.0.3.1.

After amplification, integration and filtering, the signals from the three coils in each

coil set shall be used as input values for calculating the r.m.s. values of the

amplitudes of the magnetic flux density vectors in both frequency bands. It is

permissible to calculate the r.m.s. value for each of the coil signals and use the root

of the squared sum of those r.m.s. values as the test result.

The measuring time shall be sufficiently long to enable measurement with an

accuracy of ≤ 5 % at 50/60 Hz.

The alternating magnetic field meter in band I and band II shall be capable of

measuring down to at least 40 nT in band I and down to 5.0 nT in band II.

The alternating magnetic field meter in band I and band II shall be calibrated using a

Helmholtz-type calibration coil as shown in the Figure B.4.0.3.2. Calibration set-up.

Calibration shall be performed with sinusoidal fields at the amplitudes and

frequencies specified in Table B.4.0.3.3.

Recorded values for these calibrations shall not deviate more than ± 5 % from the

nominal value. Due to the nature of the specified filters the deviation at 1 kHz shall

be calculated from 180 nT and 1800 nT and at 120 kHz from 24 nT and

240 nT.

The calibration shall be performed for each of the three individual coils separately

exposed and for one situation where approximately the same flux density passes

through all three coils.

Mandate 1. The requirement applies to plastic parts in all assemblies and sub-

assemblies.

Exempted are printed wiring board laminates, electronic components and all kinds of

cable insulation.

Mandate 2. The requirement applies to the whole of the Projector product, including

components, parts and raw materials in all assemblies and sub-assemblies e.g.

batteries, paint, surface treatment, plastics and electronic components. Printed Wiring

Boards are also included in the requirement.

HBCDD has been identified as a Substance of Very High Concern in accordance

with EU REACH criteria. The main application of HBCDD in EEE is as a flame

retardant in HIPS plastic being used for closures and structural parts of different

types of EEE. TCO Development considers that the use of HBCDD in EEE is not

deemed essential as technically suitable alternative substances and materials are

available and already used extensively today.

Maximum concentration values tolerated for a restricted substance (including

decaBDE) is 0.1 % by weight in homogeneous materials.

Fluoroorganic additives, used to modify the dripping behaviour of plastics in fire

conditions or to improve the processing behaviour, are exempted provided that they

do not exceed 0.5 weight percent.

Back to A.6.4.2



108 (121)

B.6.4.3 Non-halogenated substances

Non-halogenated flame retardants can be used in TCO Certified products once they

receive an accepted benchmark. TCO Development makes a list of accepted

substances available on its website. The Accepted Substances list is dynamic, which

allows new substances that have undergone a valid assessment to be added or for

accepted substances to come under reassessment in light of new scientific findings. If

an accepted substance is reassessed and given a benchmark score lower than 2 TCO

Development reserves the right to remove the substance from the accepted substance

list. Any substance to be removed will be set a sunset date. The sunset date shall give

adequate time (at least one year) for equipment manufacturers to switch to a flame

retardant alternative.

When considered necessary, TCO Development reserves the right to request a

substance undergo further assessment in order to assess the completeness, quality

and validity of a draft benchmark score, such as a GreenScreen Verification

assessment.

Full GreenScreen Assessments of substances are made publicly available on

databases such as GreenScreen Store http://www.greenscreenchemicals.org/gs-

assessments/chemicals or IC2 (Interstate Chemicals Clearinghouse)

http://theic2.org/hazard-assessment or Techstreet

B.6.4.3.1 Compliance procedures (See also Flow chart B.6.4.3.1)

- First contact your suppliers such as the plastic and panel manufacturer and ask

them to confirm that they only use flame retardants including substances on the

accepted substance list.

- If all flame retardants only include substances on the Accepted Substances List the procedure is as follows:

1. Sign template A.6.4.3 and submit it to the approved environmental verifier. When the

verifier considers all environmental documentation is compliant they will issue an

Environmental verification to the applicant.

- If any flame retardant is used that contains a substance that is not on the Accepted

Substances List then it will need to be added before approval can be given by the

environmental verifier. For this the procedure is as follows:

1. Contact TCO Development directly to see if we have any additional information on

the substance: Reasons for the substance’s absence can be that the substance has

received benchmark 1, no assessment has been conducted or it has a benchmark score

U (unspecified) due to many data gaps.

2. If TCO Development requires the substance to be benchmarked, we recommend you

contact your supplier and inform them that the substance will need a GreenScreen

assessment by a licensed profiler. The list of licensed profilers can be found on the

CPA website at http://www.greenscreenchemicals.org/professionals/profilers

3. A draft report per substance (not flame retardant) is assembled from the available

information (literature search, structural similarity comparison, expert judgment) by

the profiler.

4. It is the profiler that sets the benchmark score per relevant substance, which is valid

for 3 years. Substances are assessed at 3 year intervals since mandates are revised and

more data and new knowledge on the substance may lead to other results.

Note: All assessments and reassessments shall be conducted by licensed profilers.

5. Full GreenScreen assessments per substance shall be submitted to TCO

Development for final approval before the Accepted Substances List can be updated.

6. Once a substance is added to the list and the verifier identifies them, then they will

issue the environmental verification to the applicant (see above point 1 under: If all

flame retardants only include substances on the Accepted Substances List the

procedure is as follows)



110 (121)

Flow chart B.6.4.3.1. The Compliance procedure

B.6.4.3.2 Grace period Applicants signing mandate A.6.4.3 have the option to seek a grace period in order to

give them time to assess flame retardants used and substitute these if necessary. The

request for a grace period shall be sent to TCO Development together with a

description on why a grace period is necessary and a timeline for the GreenScreen

assessment and/or substitution. On receiving this request, TCO Development will

conduct a risk assessment as to whether the applicant can be given a grace period to

show compliance. If a grace period is not granted, then the applicant is required to

ensure that all used non-halogenated flame retardants only include substances that

are on the TCO Accepted Substances list before a certificate can be issued to them.

After the grace period, if an approved a grace period exceeds the due date, then the

verifier shall contact TCO Development and a course of action will be decided after

talking first with the applicant.

B.6.5.1 Lifetime extension

That spare parts shall be available for three years from “the time that production

ceases” is only applicable to the production of the specific Projector, certified by the

brand owner according to TCO Certified.

Regarding spare parts:

If a part of a product is broken (e.g. bezel, stand) the end user shall not need to

replace the whole product, only the broken part. The broken part shall be

possible to replace with an equivalent part (this part does not have to be

identical to the broken part).

When the cost for replacing a broken part (e.g. panel) exceeds the cost of

replacing the whole product, then that part need not be considered as a spare

part under this mandate.

B.6.6 End of life

B.6.6.1 Material coding of plastics

If the amount of flame retardant exceeds 1 % by weight the coding shall be

complemented in accordance with ISO 1043-4.

The requirements also apply to plastics in the LCD panel, however labelling of the

light guide may instead consist of the application of a label in close proximity, for

example PLASTIC LIGHT GUIDE:>plastic type(s)< or >PLASTIC LIGHT

GUIDE:plastic type(s)<. Labelling of Plate diffuser (not thin plastic film diffuser)

shall follow the same rules as for the light guide.

The requirement does not cover other thin plastic films in the panel due to difficulties

in labelling these.

Back to A.6.6.1

B.6.6.2 Take back system

Tick the box of the option chosen.

If the applicant chooses option 1 (Product only sold on markets with WEEE

legislation or similar) and signs the declaration, the requirement is fulfilled.

If option 2 or 3 (World-wide product take back or One additional market lacking

WEEE legislation where product take back is offered) is chosen, the declaration must

be signed and the applicant must provide a short description of how the take-back

system on that market works. This can also be done by giving a reference (for

example a link to a website) to the representative, associated company or affiliate

taking care of the take-back system on that market.

In case of option 3 the applicant must also provide the name of the market (country)

where a take back system is provided.

TCO Development has no requirement on the take-back system being free of charge.

It is important to point out that any recycling and waste export control legislation in

countries where the applicant company operates must always be met.

B.7 Socially Responsible Manufacturing

B.7.1 Supply chain responsibility

B.7.1.1 General Clarifications

The mandate is a social performance mandate and criteria are based on the eight ILO

(International Labour Organization) core conventions and local legislation. The

mandate stipulates the minimum standards for Code of Conduct, Inspection and

Corrective Action engagement of the brand owners regarding the situation at their

own and/or their supplier’s manufacturing facilities of TCO Certified products.

B.7.1.2 Background information

B.7.1.2.1 SA8000

SA8000 is based on the UN Universal Declaration of Human Rights, Convention on

the Rights of the Child and various International Labour Organization (ILO)

conventions. SA8000 is a global social accountability standard for decent working

conditions, developed and overseen by Social Accountability International (SAI).

SAI contracts with a global accreditation agency, Social Accountability

Accreditation Services (SAAS) that licences and oversees auditing organisations to

award certification to employers that comply with SA8000.

B.7.1.2.2 Electronic Industry Citizenship Coalition (EICC)

The Electronic Industry Citizenship Coalition (EICC) is a group of companies

working together to create a comprehensive set of tools and methods that support

credible implementation of the Electronic Industry Code of Conduct. The EICC

Code of Conduct is at the core of member requirements and members are required to

commit to it, spread that commitment to their supply chains and undertake a range

of assessment activities to ensure they are accountable to their commitment to the

Code.

The EICC VAP (Validated Audit Process) is a factory audit framework for

identifying risks and driving improvements and robust management systems for

labour, ethics, health, safety and environmental conditions in the supply chain. It is a

third party validated audit service that provides an independent audit of a supplier,

potential supplier, and/or a company’s own facilities.

For more information visit: http://www.eicc.info/

B.7.1.2.3 Grace Period.

Brand owners signing mandate A.7.1 for the first time have the option to seek a 12

month grace period in order to give them time to improve their supply chain

management systems. On receiving this request, TCO Development will conduct a

risk assessment as to whether the brand can be given a grace of 12 months to show

compliance. If a grace period is not granted, then the brand is required to make all

required improvements and actions before a certificate can be issued to them.

After 12 months, if an approved a grace period exceeds the due date, then the verifier

shall contact TCO Development and a course of action will be decided after talking

first with the brand owner.

then the third party audit report does not have to be reviewed by an approved

Social Reviewer. It is enough to send a copy of the SA8000 certificate to the

Environmental Verifier and a copy of the audit report with the application to

TCO Development.



115 (121)

5. Submitting the annual corrective action plan (CAP) if relevant.

The Brand owner must submit one corrective action plan (CAP) for review for

any non-conformity found in the submitted audit report to an approved Social

Reviewer..

SA8000: If the first tier manufacturing facility is certified according to SA8000

then then the CAP does not have to be reviewed by a n approved Social

Reviewer. It is enough to send a copy of the SA8000 certificate to the

Environmental Verifier and a copy of the the CAP with the application to TCO

carried out at one of their first tier facilities producing TCO Certified products.

The following applies:

The Brand owner may choose the third party Audit firm.

Third party auditors used by the Brand owner to carry-out the factory

inspection and issue the report shall have documented experience of carrying

out social auditing. The auditor should have undergone the SA8000

Advanced Auditor Training or an equivalent training course

A third party is considered to be a person or body that is recognised as being

independent of the parties involved, as concerns the issue in question. Parties

involved are normally the Brand owner (first party) and purchaser (second

party).

Board and addressed by management.

o The code of conduct shall relate to the manufacturing of the specific

product being certified.

Supply chain being informed of the code of conduct:

o Examples may be that the Brand Owner has translated the Code of

Conduct into local languages. This shows that the company has made

efforts so that management and employees are able to be informed

about the code’s content in their own language.

o Or the company has conducted training on the Code for employees

and/or management at production facilities.

o Another common way to inform production facilities can be to have

them fill out a questionnaire (self-assessment) on compliance with the

code.



116 (121)

Audit report reviews: Central to the compliance options is the review of the

factory audit report conducted by a third party Social Reviewer approved by

TCO Development. Audit reports sent for review shall not be older than 12

months. It shall be authentic, conducted by an auditor with the correct

competence and cover the relevant manufacturing site.

Corrective Action Plan (CAP): If there were findings during the factory

inspection then a CAP (remedial plan plus timelines and evidences) for the

findings shall be submitted for review together with the audit report. This

CAP will be evaluated for effectiveness by the Social Reviewer. A judgement

on the remedial effectiveness and a summary will be given in the Verification

Report issued by the Social Reviewer..

The approved Social Reviewer: All supporting documentation shall be

reviewed by a third party approved by TCO Development. This reviewer

shall not be the same person that conducted the factory audit. The reviewer

has the authority to review and verify the following types of documents:

o Code of conducts

o Communication of the code of conduct

o Audit reports,

o CAPs,

o SA8000 certificates/audits

o Supporting documentation

After the review the Social Reviewer issues the Audit Report Verification

document to the Brand owner or the applicant. It is the final responsibility of the

Brand owner to submit this document to TCO Development to show that they are

aware of the situation at the factory and accept the report.

A verification report issued by the approved Social Reviewer is valid for 12 months

from the date of the Brand owner’s first issued TCO Certified certificate covering

mandate A.7.1. The verification must be updated annually. The list of approved

Social Reviewers is found at: www.tcodevelopment.com

B.7.1.3.4 On-site inspection initiated by TCO Development (Spot-checks)

TCO Development reserves the right to require full audit reports and conduct or

commission on-site inspections at first tier manufacturing facilities to verify that the

Brand owner is fulfilling the obligations according to this mandate. The planning of

social audits will be done in cooperation with the Senior Management Representative

appointed by the Brand owner. Audits will be implemented by TCO Developments

partner organisation for the actual geographic region. Social audits initiated by TCO

Development will be realized on a judgement sample basis, in each case decided by

and financed by TCO Development. Results from the audits will be shared with

audited factory (both management and worker representatives) and all the brand

owners listed as using the audited factory in order to create a combined effort toward

implementing the CAP. For TCO Development, the spot-checks and all other

submitted reports contain valuable information on social performance, making it

possible to translate findings into metrics and then measure improvement through

code of conduct and audit methodology.

Back to A.7.1




117 (121)

B.7.2 Senior Management Representative


The mandate underlines the importance for the Brand owner to appoint a senior

management representative who, irrespective of other responsibilities, has the

authority to ensure that the requirements of this mandate are met. This aims to create

an open and transparent dialogue between TCO Development and top management at

the brand owner company.

B.7.2.2 SMR review

The intention of the review of the SMR is to ensure that the SMR has the necessary

authority and is working in a structured way in implementing the Brand owner’s

code of conduct. The SMR may bring assistants to the review meeting if needed.

The following questions will be asked of the SMR:

1. The SMR will be asked questions on how the communication of the Brand

owner’s code of conduct to first tier factories has been done. (See point 1 of

the self-assessment questionnaire)

2. The SMR will be asked questions about the Brand owner’s audit schedule

and about some of the audits that have been done. (These reports may be first,

second or third party audits).

3. The SMR will be asked to show examples of progress for some corrective

action plans.

4. The SMR will be asked to fill in the self-assessment questionnaire on

proactive work (point 2-19) by TCO Development (B.7.2.2.1) prior to the

review and explain in more detail the Brand owner’s proactive work to

implement their code of conduct during the review. The SMR might be asked

to show supporting documentation for this. The self-assessment questionnaire

does not have to be reviewed by a verifier approved by TCO Development. It

is sent directly to TCO Development prior to the SMR review.

The Questionnaire and Guidelines for the assessment are public and can be

downloaded at: www.tcodevelopment.com




118 (121)

As long as the SMR is able to show the relevant documents and explain the Brand

owner’s structured work to implement their code of conduct the review is accepted.

If the SMR is not able to get hold of necessary documents or if he/she cannot explain

about the Brand owner’s structured work to implement their code of conduct the

review is not accepted.

The review may be done through an online meeting. However, it is necessary that

documents can be shared (during or prior to the meeting) and that the communication

quality is adequate for full understanding.

If it is not possible to set up an online meeting that fulfils the requirements above or

if the review does not give an acceptable result then TCO Development has the right

to require the SMR to be reviewed by a third party auditor paid by the brand owner.

The report from this review is then sent to TCO Development.

TCO Development also has the right to require a face to face review of the SMR. For

this type of review, TCO Development will cover their own costs.

B.7.2.2.1 Self-assessment questionnaire on proactive work

The self-assessment questionnaire is provided by TCO Development and is a set of

questions covering such areas as the implementation of the Brand owner’s code of

conduct, auditing and follow-up of social criteria, trade union rights and

representation, activities to avoid discrimination and create an open dialogue with

suppliers.

The Brand owner SMR is responsible for answering all questions and providing

documented proof of how it supports its suppliers in these areas. Each answer is

colour graded full- (Green), partial- (Yellow) or non- (Red) compliance level.

In order to highlight the need for progressive improvement and level the commitment

between different brands, the questionnaire is required to be submitted annually

during the SMR review. However, the self-assessment questionnaire does not have to

be reviewed by a verifier approved by TCO Development. It is sent directly to TCO

Development prior to the SMR review.

There is currently no minimum level required for the proactive work reported in the

questionnaire (point 2-19) in this generation of TCO Certified. The data collected in

the questionnaire on proactive work will be used to risk assess Brand owners for the

spot-check program. In this program TCO Development make annual third party

factory audits according to the code of conduct on a number of Brand owners first

tier factories. The questionnaire is also intended to measure the progress in the

industry and to be used as a basis for future criteria development in this area.

The Questionnaire and Guidelines for the assessment are public and can be

downloaded at: www.tcodevelopment.com

B.7.3 Conflict minerals


The mandate mainly focuses on the 3T+G minerals which are being mined within the

Democratic Republic of Congo (DRC) region and used in a wide range of computer

products. Once refined the origins of minerals are hard to trace, therefore we are

recommending the importance of participation with legitimate in-region initiatives

that directly benefit people in the conflict-affected regions. However, since the

number of participants for in-region initiatives are low at this stage we also accept

involvement in smelter/refinery certification programs since they complement in-

region initiatives. Also we approve brands that can satisfactorily provide proof that

they have adopted the OECD Due diligence guidance, since it provides a framework

for brands to ensure that they respect human rights and do not directly or indirectly

contribute to conflict.

B.7.3.2 Background information about the initiatives

TCO Development is demanding brands address the conflict mineral concerns of the

private and public sector while delivering solutions that benefit those involved in the

responsible minerals trade in the DRC. TCO Development considers participation in

the following initiatives facilitates that goal. It is TCO Developments opinion that the

OECD Due Diligence Guidance for Responsible Supply Cain of Conflict-Affected or

High-risk Areas is the most ambitious approach in the list.

The OECD Due Diligence Guidance for Responsible Supply Chains of

Minerals from Conflict-Affected and High-Risk Areas (“the Guidance”).

Brands require suppliers to disclose their sourcing origins of conflict minerals

by using a questionnaire template such as the EICC ‘Conflict Minerals

Reporting Template’ or similar in order to prevent the potential use of conflict

minerals.

iTSCi - ITRI represent tin producers and smelters. This program is a supply

chain initiative to verify and trace minerals from the mine to smelter

(traceability tagging). Although full membership is focused on upstream

companies (Mining, Smelters etc) an Associate membership for downstream

companies exists (manufacturers etc). Associate members contribute to the

financing of the iTSCi program and so keep informed of initiative activities,

specific mining sites whilst they support development in Africa.

For more information:

Conflict-free Tin Initiative (CFTI); sources conflict-free tin from the South

Kivu province of DRC that implements the ITRI Tin Supply Chain Initiative

(iTSCi) the due diligence and traceability system

The Public-Private Alliance for Responsible Minerals Trade (PPA) is a multi-

sector and multi-stakeholder initiative that provides funding and support to

systems that trace and certify mineral supply chains in the DRC and Great

Lakes Region. http://www.resolv.org/site-ppa/

Other relevant in-region initiative. Initiatives not given in the list but prove

active commitment to an initiative that aims at increasing legitimately sourced

minerals.

Examples of other relevant initiatives that are approved:

- Solutions for Hope (SfH); sources conflict-free tantalum from the

Katanga province of DRC (incorporates the iTSCi process and CFS

program).

- The Certified Trading Chains initiative (CTC) is a program supported by

the German government and certifies mines to defined performance

standards

Member of the EICC & GeSi Conflict-Free Sourcing Initiative (CFSI).

Members contribute to a number of tools and resources including the Conflict

Minerals Reporting Template; supporting in-region sourcing schemes and the

Conflict Free Smelter Program (identification of Smelters and Refiners that

source conflict-free minerals).

B.7.3.3 The verification process

At least one of the options in the mandate box shall be marked. Every initiative the

Brand is a participant in shall be provided. The following shall occur before the

verifier may issue a verification of compliance.

The template shall be completed by the responsible person at the brand owner

company.

The brand shall complete the TCO Certified Conflict Mineral Questionnaire

and submit it and any required supporting documents for review. The verifier

then assesses compliance and issues the verification report.

Supporting documents

If the brand has a management system covering conflict minerals within its

supply chain which it states are based on the OECD Due Diligence

guidelines, then a supporting document that outlines those due diligence

measures shall be submitted. Example of proof are:

o Due Diligence Roadmap, Sustainability report or Conflict Mineral

Report asserting the OECD five step framework.

o Link to where information/findings are posted on the brand’s website.

The brand shall provide a copy of its conflict mineral policy and state where

the information is made public.

If the brand is part of an in-region initiative or the EICC CFSI, then

supporting documents or links to relevant websites shall be provided to the

approved verifier in order for them to verify participation.

If the brand marks the option ‘Other relevant initiative’, then the name of the

initiative shall be entered into the template and information on the initiative

(or website) shall be submitted to the verifier and they will contact TCO

Development in order to make a joint assessment before it can be accepted as

an option. Although unlikely, any additional review fee entailed for an extra

assessment will be charged to the applicant, after receiving the applicant’s

consent.

When the application is satisfactory, the verifier notes on the verification

report the fulfilled options and the type of supporting documentation.
